Yesterday we created a multiserver Zimbra installation with 1xMTA/Proxy 1xLDAP 1x Zimbra Mail (mailboxserver) ...
LDAP & Zimbra are at the DMZ site. The MTA is accessable via internet over 443 (we create a redirect from 80 to 443). Everything works fine and is really fast. The Problem which we had is:
If you're Maill-Domain-Account you just want to admin your domain settings but zimbra uses the port 7071 for it. THe problem is, that our FW is configured to pass the port 7071, but the MTA (proxyserver& mail) doens't recognize it and we got an timeout page.
We don't want to use a third application or other things. We think that we only have to open the port 7071 and thats it .. because the proxy knows the webmail servers ...
Is anybody able to help me with that?!
